Itsuku: a Memory-Hardened Proof-of-Work Scheme

Fabien Coelho and Arnaud Larroche and Baptiste Colin

Abstract: Proof-of-Work (PoW) schemes allow to limit access to resources or to share rewards for crypto-currency mining. The MTP-Argon2 PoW by Biryukov and Khovratovich is loosely based on the Argon2 memory-hard password hashing function. Several attacks have been published. We introduce a new transposed parallel implementation attack which achieves higher performance by circumventing apparent bandwidth requirements. We then present Itsuku, a new scheme that fixes known issues by changing MTP-Argon2 parameters and adds new operations to improve memory hardness. Our scheme is built on a simple security criterion: any implementation which requires half the memory or less should induce at least a times-64 computation cost for difficulty d <= 100. The Itsuku proof size is typically 1/16 th of the initial scheme, while providing better memory hardness. We also describe high-end hardware designs for MTP-Argon2 and Itsuku.

Category / Keywords: cryptographic protocols / hash functions

Anyone we know b4h4mu7?

Biryukov and Khovratovich designed the Equihash algorithm in use by Zcash. AFAIK their latest design MTP-Argon2, or Mekle Tree Proof, was designed as a successor to Equihash with the primary function of providing an Egalitarian mining solution. Fabien reviewed this algorithm and redesigned it to be hardened against all known attack vectors along with optimized proof sizes, which is known as Itsuku. Initial spec is 2GB but in any case, even with 64GB of RAM there wont be much speedup, since the limiting factor is bandwidth and not space.

Relative Papers and work:
Equihash - https://eprint.iacr.org/2015/946
MTP - https://arxiv.org/pdf/1606.03588v1.pdf
MTP Attack - https://eprint.iacr.org/2017/497
Marc Bevand's blog - http://blog.zorinaq.com/attacks-on-mtp/

Arnaud Larroche and Baptiste Colin are two of Fabien's students at MINES ParisTech. They're the ones who wrote the Python implementation.

Why is only half to 1/4 of my hash showing at the pools? I have my bat file done correctly too.
http://mining.blue/#    is the worst.

My reds hashing fine at http://mining.blue/# . But nvidia is underperforming because of huge quantity of "share does not validate on cpu". ccminer is not so good for BBR so my greens work elsewhere.

I am unable to sync past  360 days.
says in purple words... my software not current and needs to be updated.
who has the most up to date version.

seems not very fair for only a few to be able to continue mining
I want to solo mine with the daemon/wallet. not pool.

it is good for the network also.

anyway any input will help. thanks.

Willing to sell 33000 Boolberries at a flat $10 each coin. DM if interested  Grin

Btw would like to see more exchanges. Like cryptopia binance and others. Good Luck  Roll Eyes

Please try updating to latest release and see if it resolves your issue. I've seen that error before when trying to use binaries from the boolberry.com website as it hasn't been updated since 2014-09-25 (according to https://sourceforge.net/projects/boolberry/).

Latest releases are available here:
https://github.com/clintar/boolberry/releases

Alternatively, you can compile from source just make sure you have correct dependencies. Two most current repositories:
https://github.com/cryptozoidberg/boolberry
https://github.com/clintar/boolberry/

Also, please take note that the network hashrate is the highest its ever been. You'll have much better luck mining on a pool than mining solo. A list of pools is available here:

Yea, just login to Stock Exchange and transfer your coins there, that's what I did Smiley

Bye the way - lookin good for BBR, thank you developers, and a bow

i got the latest from gitHub, but i am still having problems syncing/connecting.

I am getting this error still: "...Remote node have longer checkpoints zone( 773500) that local (550000)That means that current software is outdated"
And every single connection attempt gives this: "2017-Dec-04 11:55:59.216567 [P2P2]Connect failed to 138.201.116.10:10101

Do I just need to let it run for a few days?

edit: also this, which looks bad

v0.2.0.37 cannot be the latest...

I got it from here:
Latest releases are available here:
https://github.com/clintar/boolberry/releases

files are dated 10/11/2017, but when i install them and load up the GUI, it says Software Version 0.2.0.37
